Based on the sonARMS shooting noise model and the sonX sound propagation model, shooting noise calculations can be simulated for different weapon categories, taking into account the geographical and meteorological conditions.

The sonARMS calculation model was developed on behalf of the Swiss Federal Office for the Environment (FOEN) by the Empa’s Laboratory for Acoustics / Noise Control in collaboration with Merz Technik and implemented as standalone add-in – based on D-noise – by n-Sphere.

The sonARMS emission model describes muzzle blasts, projectile blasts and detonations as a function of the weapon category and allows calculations in accordance with Annexes 7 and 9 of the Swiss Noise Abatement Ordinance.

Are you looking for a strong partner for the calculation of shooting noise in D-noise?
We have implemented the sonARMS calculation model in D-noise – and have proven noise experts in-house.

With our expertise, you can:

• Set up your shooting noise project professionally – from data acquisition to the final calculation

• Carry out detailed assessments of buildings, apartments and undeveloped parcels – with precise allocation of sensitivity levels and floor-by-floor usage

• Plan and calculate forecasts and noise abatement measures – to ensure that your system complies with the exposure limit values in accordance with the NAO

• Have complex and reusable evaluation templates created – for precise analyses and graphics
